Clifton's Anguloa

Clifton's Anguloa, Anguloa cliftonii, is a striking terrestrial orchid in the family Orchidaceae native to the cloud forests of the Andes in Colombia, Ecuador, and Peru. The genus Anguloa, known as cradle orchids or tulip orchids, is celebrated among orchid enthusiasts for its large, tulip-shaped, waxy flowers that rock gently when moved, simulating the movement of a bee—a presumed pollination adaptation. The flowers of Anguloa cliftonii are creamy white to pale yellow, often with pink or rose spotting, and are produced singly on erect peduncles arising from the base of large, pleated pseudobulbs. The plant is a cool-growing epiphyte or lithophyte found in humid montane forest at elevations between approximately 1,500 and 2,500 meters in the Andes. Anguloa species are pollinated by male euglossine bees attracted to fragrant compounds. The cloud forest habitats of the Andes are among the world's most biodiverse ecosystems and simultaneously among the most threatened, subject to deforestation for agriculture, cattle ranching, and coca cultivation. Many Andean orchid species are also threatened by over-collection for the horticultural trade. Anguloa cliftonii is cultivated in specialist collections and is the subject of conservation concern in its native range.
